224 ATTEMPTS TO ASCERTAIN 
September 8.—Began at 11 am. Up to 3 o'clock 
only seven ants found their way to the honey, while 
about as many ran up the other pillars. The arrival of 
these seven, therefore, was not more than would 
naturally result from the numbers running about close 
by. At 3 we allowed the ants then on the honey to 
return home. The result was that from 3.6, when the 
first went home, to 3.30, eleven came; from 3.30 to 4, 
no less than forty-three. Thus in four hours only seven 
came, while it was obvious that many would have 
wished to come, if they had known about the honey, 
because in the next three quarters of an hour, when 
they were informed of it, fifty-four came. 
On September 10 I tried the same again, keep- 
ing as before three ants always on the honey, but not 
allowing any to go home. From 12 to 5.30, only eight 
came. Those on the honey were then allowed to take 
the news home. From 5.30 to 6, four came; from 
6 to 6.30, four ; from 6.30 to 7, eight ; from 7.30 to 8, 
no less than fifty-one. 
On September 23 we did the same again, begin- 
ning at 11.15. Up to 3.45 nine came. The ants 
on the honey were then allowed to go home. From 
4 to 4.30 nine came; from 4.30 to 4, fifteen; from 5 
to 5.30 nineteen; from 5.30 to 6, thirty-eight. Thus 
in three and a half hours only nine came; in two, 
when the ants were permitted to return, eighty-one. 
Again, on September 30I tried the same arrange- 
ment, again beginning at 11. Up to 3.30 seven antw
